diseaseKia K4 Exterior Design: Bold Proportions
Proportionally extended with bold styling at all four corners, aligned with the principles of Kia's “Opposites United” design direction, the K4 makes a powerful and dynamic statement.
“By combining the K4's fastback roofline and wide stance, we're splitting the visual distinction between the small and midsize segments,” said Tom Kearns, chief designer, Kia Design Center America. “The creative tension emphasized by Opposites United's design language allowed us to enhance the traditional three-body form factor.”
With an overall length of 4.7 meters and a width of 1.8 meters, the K4 is very wide and takes up a lot of space in the compact segment. Rear passengers will enjoy a class-forward ride with legroom. The standard, vertically oriented LED headlights and taillights take inspiration from the flagship EV9 model, creating pronounced edges throughout the lighting signature at the front and rear.

Come K4: Top segment ADAS
K4 improves and expands the availability of standard ADAS. Additionally, the K4 adds standard rear airbags for a total of eight.
The K4 offers the latest Kia ADAS suite including Intelligent Speed Limit Assist (ISLA), Lane Keep Assist (LKA) and Smart Cruise Control with Stop & Go (S&G with SCC). A key driver assistance technology feature on the K4 is the Forward Collision Avoidance System 1.5 (FCA-1.5), which helps detect and prevent collisions in certain situations, as well as detect vehicles, pedestrians and cyclists. While driving (FCA-CPC), as well as when oncoming vehicles turn left at an intersection (FCA-JT). Haptic alerts on the steering wheel add haptic alerts to the driver.
Optional on K4 GT-Line Turbo models, it adds the Forward Collision Avoidance System 2 (FCA-2) function and is designed to avoid passing vehicles when crossing an intersection (FCA-JC). FCA-2 is designed to provide braking and/or steering action to help avoid certain collisions or mitigate the consequences if the system detects approaching vehicles while passing other vehicles (FCA-LO); Vehicles in front of the car when changing lanes (FCA-LS); The K4's Aviva Steering Assist can help mitigate collisions with obstacles, pedestrians or other vehicles that are detected ahead, and will warn the driver in certain situations and assist the driver in steering if there is room on the road to avoid a collision. FCA is designed, in some cases, to help avoid a collision with an oncoming vehicle by providing auditory and visual warnings and applying the brakes (FCA-DO). Highway Driving Assist 2 (HDA-2) is a driver assistance system that helps maintain a distance from a detected vehicle ahead and keep the vehicle within detected lane markings on certain roads.
Apart from the standard Blind Spot Collision Warning (BCW) and Rear Cross Traffic Alert (RCTA), the GT-Line is available with Blind Spot Collision-Avoidance Assist (FCA-BCA) and Spot View Monitor (BVM). In various situations, the system can use braking to avoid a potential collision, helping to visualize and detect vehicles coming from behind and in adjacent lanes. The optional Surround View Monitor (SVM) uses cameras around the K4 to provide a 360-degree view in reverse and parking scenarios. Available Park Distance Alert is designed to add 360-degree capability for forward, side, and reverse (PDW-F/S/R) parking maneuvers.
